A cement bond log (CBL) must be submitted showing adequate cement isolation above the perforations. The casing must be pressure tested before perforating (or with a bridge plug if already perforated). An RTS with a timedrive supplement may be run. Oilbased fluids are not authorized.

Introduction to cement bond logs FEBRUARY FACT SHEET 2017 Cement bond log tools (CBLs) have evolved over the years as technology and telecommunications have advanced. From the 1950s basic single transmitter and dual receiver design with analog communication and zero reprocessing capability, industry has moved to broadband transmitters
Comparison of the full waveform to logs that are sensitive to porosity/lithology can help to evaluate the cement bond log. Caliper information from the open hole is important. Knowledge of the well mechanics and facts about, as well as conditions during, the cement job is extremely important in evaluating the measurements from cement bond logs.
A log that uses the variations in amplitude of an acoustic signal traveling down the casing wall between a transmitter and receiver to determine the quality of cement bond on the exterior casing wall. The fundamental principle is that the acoustic signal will be more attenuated in the presence of cement than if the casing were uncemented.

BASIC LOG TYPES Below is a list of the main types of logs that may be run, and why they are run. Logging While Drilling (LWD) Traditionally, petrophysicists were concerned only with wireline logging, that is, the data acquired by running tools on a cable from a winch after the hole had been drilled. However, advances in drilling/logging
Cement bond tools measure the bond between casing and the cement placed in the annulus between the casing and the wellbore. The measurement is made by using acoustic sonic and ultrasonic tools. The measurements of industrystandard sonic tools are usually displayed on a cement bond log (CBL) in millivolt units, decibel attenuation, or both.
Cement bond logs were run as early as 1958 with early sonic logs and the temperature log was used to find cement top beginning in 1933. Cement integrity logs are run to determine the quality of the cement bond to the production casing, and to evaluate cement fillup between the casing and the reservoir rock.
A Cement Evalua tion (CET*) log from a well in a Middle East carbonate reservoir. The CET tool has eight ultrasonic transducers distributed radially on a mandrel. Emitted acoustic energy res onates the casing if there IS no cement bond and shows up as white on the image in track 3 of the log. A good bond shows up as black. The top third of the
CementBondLog Interpretation Reliability. Two kinds of cementbondlog (CBL) tools are run as part of a standard cementevaluation program. The effectiveness of these tools and their evaluations often are challenged, and they are not regarded as a replacement for reservoir interzonalcommunication tests performed between producing reservoirs.

The surveys included in this group are: Gamma Ray Neutron Temperature Pulsed Neutron Cement Bond Log Some of these surveys like the gamma ray, neutron and temperature logs can be run in both open and cased hole wells.
Apr 11, 2019· The setting time depends on the type of cement, temperature, pressure, and the use of setting accelerants. Excess pressure on the casing should be avoided during the curing period so that the cement bond to the pipe is not disturbed. A cement bond log documents has an evaluation of the integrity of cement work performed on an oil well.[1]

CEMENT DESIGN IMPACTS ON LOG RESPONSE The closer the cement density is to that of the drilling fluid used, the more difficult it is to distinguish between a solid a liquid The lower the compressive strength of the cement, the more difficult it is to "find" on a log, and requires use of specialty tools and evaluation software
